  1. [Off Topic] Electron Micrographs of New and Used Abrasives

    I really liked this YouTube video which has a field engineer explaining many electron microscope pictures of new and used grinding wheels. I was surprised at how stringy swarf is from the abrasion...

    I'm curious about this too! I'm wondering if owners of convex edges would be willing to make a "cast" of their knife edge. You could make a cast by first coating the knife with something like oil...
  3. I don't have much experience with convex edges,...

    I don't have much experience with convex edges, but I've read about other people who have used guided-rod sharpeners to make convex edges.

    First of all, some of them use an idea very similar to...

    Hi Everyone,

    I'm interested in how to precisely capture the silhouette shape of a knife. After the shape has been captured, then we could use software to determine the best way to clamp a knife...

    Here is a new version. This will be the last version for quite awhile, I think.

    Changes:
    Expanded some of the discussion about gimbals, universal joints, and spherical joints in Chapter 3....

    Here is the latest version. The contour plot visualizations were added to the report in an appendix.

    I'm back from the holidays and had a chance to do some visualizations.

    So, let me mention what kind of data we're trying to visualize:

    Suppose we have a Chef's knife that we want to sharpen on...

    Following a suggestion, I have added three knives to the report: An 8" chef's knife, a 10" khukuri, and the Spyderco LionSpy pocket knife. In the report is a new section,"Case Studies of Curved...

    Hi Jack,

    Thanks for having a look at the report. Sorry if it's a bit complicated, but I'm glad the videos helped and that you found some parts of it to be useful. :)

    The report may be more...

    Hi Jack,

    If parts of the report are hard to understand, then I'm happy to discuss and/or try to explain them better. Just ask me. :) I can't promise that I'll come up with something better,...

    In some more detail:

    In the report, there is an entire chapter on dihedral angles. They are defined in Chapter 2, and some of the ways they can be changed are also described.

    Many different...

    @jackknifeh,

    The answer to your questions are in the report. :)

    @jackknifeh,

    Can I nudge you to read the report? It's written for you and the knife community.
    You'll really enjoy it; most of you intuition is on the right track. But I think you are missing a...

    @jackknifeh,
    Thanks. Glad you liked the sharpening rig I made.
    I like your idea of Edge Guide Blocks (EGB). I may have to make some. :)

    @Evil D,
    Oh, I mean that the shape of the knife, like...

    @Evil D
    I agree; if you don't move the blade in the EP, then the skill required is much less. Also, yeah, clamping properly on the WEPS takes a little time. Personally, I don't mind that. btw, if...

    Hi Brock O Lee,

    The Edge Pro and the Wicked Edge systems are very good. Both are accurate and consistent. It is...

    I was asked to do an analysis of sharpening a khukuri knife at 10 degrees per side. The analysis here is for a WEPS-Gen1

    I started with photo of a khukuri that I found from www.KnifeCenter.com. ...

    Hi WorkingEdge,

    You are correct. :) If the central mast is vertical, and the guide rod and sharpening stone are horizontal, then the stop-collar-trick becomes perfectly accurate (in theory). ...

    I forget, but I think H-1 is a steel which uses nitrogen instead of carbon to increase hardness? I'll defer to a metallurgist or someone who knows better for a real answer. (I might be confusing...

    @jackknifeh:

    Hi, I think you have the right idea, but I'm not 100% sure. I wasn't able to completely decode your explanation. Could you try reading the first few chapters of the report itself? ...

    @ Jackkneifeh:

    I do like MadRookie's EP modification with a spherical joint (spherical rod end). It is discussed in the report, on the chapter on the Edge Pro Apex. In that chapter has a photo of...

    @ Jackkneifeh:

    I had some discussions with the owner of EdgePal in the forums. I had some trouble communicating with him due to a language barrier (he is not a native English speaker from what I...
